Trucking in North America vs around the world

What is missing on the trailers?

 

Underrun Protection..?

 

466500 lbs on 6axles, also in on video 323.000 on 4axles

Truck axles are made by MB licence from 1988.
I am wondering what kind of tires are these

 

Yup.you nailed it.

Do you know why they don't have the underrunprotection?

 

Also see mudguards on trailer, you cant get approval here without full, they got only 1/4.

This is weight reason, They cut everything to keep weight down. Strange it has original MB mudguards on rear axle, they weight 50kg, aftermsrket full size starting from 15kg.

 

Impressive. They seem to average between 36-40 tons per axle. Isn't MB's most heavy duty rear end rated for 32 tons?
I suppose the guy driving the 8x4 with 146 tons has pretty strong arms to steer it.

 

you mean 64 to 69 and 69 to 73?
thanks, how many roads allow 74t? is that really restricted?
74t for tankers? for adr or only food stuff? in FI they can have 68t on 4+4 adr.

 

i mean more people would be able if they can try, since they are forcing 14.9m semitrailers lately i guess there will be even less of them.
we have 3axle lowloader from schwarzmueller, it is bit difficult to reverse it with 4axle truck, too short overhang, needs lot of space
my father teach me one thing, never let your corners to cross.
since trucks are running much faster drivelines (overall with gearbox 30%) it becomes much more difficult to reverse it, also lack of clutch pedal dont help.
my brother drives 4x4 with 4axle semitrailer. i spec 3.6m wb, he says it really helps.

 

we bought some trailers from germany that came without it, we get special approval from authority and they work normally without, in some rare cases with rigid trucks where you have metal toolboxes you dont need it too.

 

i have never seen anything similar or even close to this. worst i saw before is 176t on 7axles.
yes 2x16t for on road conditions, if you go to mines etc you can get more with approval.
from real world experience i can say that 2x8t front axles and 2x13,4t rear works fine with up to 55t gross, above that you need 9t front axles. mb allows you to spec stronger springs than axles, for example 16t springs for 13,4t axles or 19t springs for 16t axle for obvious reasons.
now volvo offers 2x19t and scania 2x18t with up to 2x21t (if it is not possible to overload it), scania has front axles with 11t (12t with restricted speed to 40kmh as there are no strong enough tires), but both of this is not for road
